IMPROVEMENT IN COAL AND ORE WASHERS.

Specification forming part of Letters Patent No. 183,215, dated October10, 1876; application led July 11, 1876.

To all whom it may concern:

Beit known that I, ANTHONY BOWSE, of Nesquehoning, in the county ofOarbon and State of Pennsylvania, yhave invented a new and Improved Coaland Ore Washer, ot' which the following is a specitication:

Figure 1 is a central longitudinal section. Fig. 2 is a transversesection of Fig. 1.

Similar letters of reference 'indicate corresponding parts.

My invention relates to apparatus for washing coal and ore for removingimpurities; and it consists of a jig that receives the coal or ore and avolume of water, and is made to vibrate vertically by means ofeccentrics, and four wings or paddles carried by a suitablyarrangedshaft stir the water, and throw the coal over'the side of the jig, whilethe impurities pass out through openings in the bottom of the jig, whichare controlled by valves.

A is a box, supporting two horizontal shafts, B and O, which are gearedtogether by the spurwheel D on the shaft B and pinion E on the shaft O.The wheel and pinion are proportioned so that the shaft O makes tworevolutions to one of the shaft B. In the box A a jig, F, is placed, theends of which are prolonged upward, and fitted to the eccentric a. Inthe bottom of the jig are apertures b b, &c., for the continuous outflowof water, and also the apertures 0 c, &c., which may be partly closed bythe valves d, the said valves,

being operated by a lever, e. f f fHf are wings or vanes attached to theshaft B at right angles to each other, and so placed in relation to thejig that they will. dip in and stir the water in the jig. An apron, g,is attached to the side of the jig, and extends over the side of the boxA. A plank, h, is placed across the side of the jig to deflect theintlow ing current of water. The bottom of the box A is inclineddownward toward the end G. H is a partition in the box A, which isprovided with a sliding. gate, t', covering a gateway in the partition.I is a sliding gate that closes a gateway in the end of the box A.

The operation of my improved coal-washer lmay be described as follows:Goal and water are introduced through a suitable sluice into the jig.Motion is imparted to one of the shafts B O, when, by virtue of theirbeing geared together, both are revolved. The motion of the eccentric a.imparts a verticallyreciprocating motion to the, jig F, which constantlyagitates its contents. The heavier impurities go out through tbeapertures b or c, while the coal is thrown over the apron g by everyalternate wing'ff, as the jig is raised twice at every revolution ot'the shaft B, bringing the apron g upward in time to nearly touch thealternate win gs.

Anything that is of suficient size toobstruct the apertures b and c maybe let out by opening the valves d.

In working the machine, the gates I and t are opened in alternation toallow the refuse matter topass out.

Having thus described my invention, I claim as new and desire to secureby Letters Patentv The combination of jig F, having apertures b c,valves d, and apron g, with the eccentric a and wings f ff"f",substantially as and. for the purpose specified.

ANTHONY ROWSE.
